Abstract
A method for the efficient management of a fleet of electric vehicles in a target area couples vehicle dynamics and battery dynamics modeling with environmental factors to accurately incorporate the impact that the environment has on the range of the battery into the placement of the chargers by simulating trips of fleets of electric vehicles. The vehicles can be of various types, for example, motorcycles, cars, trucks or aircraft, and will each have their battery state of charge monitored as they traverse a simulated trip through the target area.
Claims19
A method for managing a fleet of electric vehicles in a target area, comprising:
- dividing the target area into one or more geographic portions;
- assigning one or more nodes to each geographic portion;
- simulating a plurality of trips of a plurality of simulated electric vehicles through the target area, each trip comprising a series of the nodes between a start node and an end node;
- tracking, during each simulated trip, depletion of a charge of each simulated electric vehicle, based on a vehicle dynamics model of the electric vehicle and a battery dynamics model of the electric vehicle executed by a computer;
- and
- identifying hotspots as areas of the target area wherein the charge of vehicles tends to be below a predetermined threshold.
